It’s free and fun for me. I wanted to learn docker and various networking stuff. For normal end users, I don’t think there’s any benefit like you pointed out

Self-hosted bitwarden. Highly recommend

It definitely is confusing, and I didn’t full grasp it when I did it 😅

The installation process will vary depending on your OS. I have a synology, so I followed this walkthrough and some youtube videos as well: https://mariushosting.com/how-to-install-bitwarden-on-your-synology-nas/ but QNAP, FreeNas, etc will have their own install process. They should be pretty similiar, though, if you use docker.

Self-hosted bit warden works like a charm plus you get to learn reverse proxies if you use docker on a Nas, it’s pretty fun, would recommend
